Most likely, yes. Only way to be sure is to check the wiring, but the RCD was probably put there to protect the lights, though as far as i know, they dont neccesarily need RCD protection.
Is the 16A MCB JUST for these lights? If so, I would change it for a 10A or 6A one.
An alternative would be to treat it as a 16A radial, and put each lighting circuit an a switched FCU with a 2A fuse in it. Then as well as being independently switched and isolated, they would be independently fused as well, so a single fault would not take them all out (unless the RCD tripped) Thanks JohnD,getting a sparks to change some of the lighting!!Info was helpful and the lights are switched with normal light switches but i'm going the fcu way,thanks again.
(I suppose each external lighting circuit already has some kind of switch so you can turn it off when changing bulbs or depending on need?)
